There are several able window 'ventilators and it more especially "different locations for these concave areasythe consists of the features pointed out in the claims. purpose of which is to hold the ventilator in the The purpose of my invention is to provide a different tiltable positions I, II, and III shown 5 window ventilator that may be made as a unit in Fig. l. L Y 5 for standard-width windows or adjustable length- The ventilator proper is formed of a single wise for different width windows and at the same sheet 6, which is bent to include the inwardly protime maybe tilted to different positions so as to jecting angleof the ends.

When the ventilator is in the position I the air 45 The ends I thru the medium of pivot screws l1 currents will be directed practically parallel to and nuts 29 hold the ends against the supporting the inside of the window in a vertical direction plates Ill.

The plates Ill are formed pleasant and less stormy weather it may be tilted lengthwise thereof with a U-shaped projection ll into the positions II and III, and modifications 50 and parallel thereto with a narrow U-shaped of these positions may be secured by tilting the channel I2 in which any suitable felt or other ventilator on the pivot screw to intermediate popacking l4 may be placed. On the projection II sitions. In such positions there will be sufficient below the long slot IS a convex circular enlargetension endwise of the ventilator on the end ment I5 is formed. A corresponding concave plates between the raised surfaces I5 and i6 to 55 hold the ventilator against sliding to another point.

In Figs. 1, 4, 5, and 6, the ventilator is shown with separate ends I. If desired, it can be made altogether in one piece so as to include the end portions as shown in Fig. '7. The sheet 6 is bent at 34 lengthwise of the ventilator and perpendicular to this the triangular end portions 3| and 32 are bent at 30 perpendicular to the face of the sheet 6. These triangular portions 3| and 32 are formed the same at both ends of the sheet and the portion 3| has formed therein the long slots 3, short slot 4 and an enlarged opening 5 at the end of the slot 3. The. triangular portion 3| may have an extension 33 which will overlap the triangular portion 32 on its inside or outside as desired. Where the two portions 32 and 33 overlap they may be spotwelded to each other and two of the convex portions l6 may be formed on this overlap.

What I claim is:--

1. In tiltable ventilators, a triangular shaped end plate having a long slot formed therein and a short slot perpendicular thereto, a plurality of concave-convex areas on the end plate, a supporting plate, a raised projection thereon said projection having a lengthwise slot, a reverse groove formed lengthwise of the plate, a felt packing in the groove, a pivot screw passing thru the slots of the end plate and into the slot of the supporting plate, and means for retaining the pivot screws against accidental displacement.

2. A tiltable ventilator comprising a member closed on the ends and on two sides one of which is louvered and open on one side, a pair of supporting plates, and means for selectively holding the ventilator in different tiltable positions on the supporting plates beneath a raised window to limit the passage of air through the louvres.

3. A tiltable ventilator of triangular cross-section closed on two sides one side of which is provided with louvres and a third side remaining open, flanged ends to which the two sides are secured, a. pair of slotted supporting plates secured to the window frame, and means for pivoting the ventilator adjacent the inside window stops on the plates in a plurality of positions.

4. A tiltable ventilator having a plurality of longitudinal parallel faces one face being open and the other faces being closed, louvres formed in one face adjacent a closed one, closed ends to the ventilator, a frame, a bottom member of the frame, a sliding closure in the frame, means for pivoting the ends of the ventilator to the frame above its bottom member, and means for retaining the free edge of the closed face that is'adjacent the louvred face in engagement with the bottom member of the frame while the free edge of the louvred face is in engagement with the opened sliding closure so as to thereby prevent the passage of air past the closure opening except through the louvred face regardless of the angular relations of the faces to the frame.
